MB15F8xUL Series
Fractional-N / Integer dual
PLL Frequency Synthesizers


DESCRIPTION Packages
The Fujitsu MB15F8xUL series dual PLLs are serial input
Frequency synthesizers. The Fractional-N PLL operates up to 2.6
GHz and the integer PLL operates up to 1200 MHz. They have
built-in dual-modulus prescalers enabling pulse swallow operation
and fixed or selectable fractional modulo. The latest advanced
BiCMOS technolog

Evaluation Systems Designing a complex subsystem, such as a PLL, is no easy task. Therefore, Fujitsu has made available an evaluation system to aid in the development of reliable frequency synthesizers. Each evaluation system consists of two PCBs, controlling software, and instructions. The RF PCB is laid out to allow the target MB158xUL to be optimized for the chosen application. The RF board is only semi-populated, which allows the user to configure it to fit the application.
